Hi Jesse,
Yes, I would agree, your little button seems alittle "off". I would do the set up that should help sick birds. A heat lamp or source of warmth should help...possibly a lamp placed over half of his cage and or a heat pad - again, over half of his cage so he has choice to be in or out of the heat( I would cover his cage with a towel or blanket too). Offer some hard-boiled egg yolk and any goodies he likes...but the egg is good for protein and they usually like it. In the meantime, monitor his progress, stool form etc. If he continues to behave sickly, it would be a good idea to take him to a vet who deals with birds...they may want to look at a stool sample also. Has there been any change to his diet, what do you feed him and has there been a change in his surroundings or additional stress?
